Combining More Than Two Waves

In a more general case, we might want to find the resultant of more than two sinusoidally varying waves at a point. The general procedure is this:  1. Construct a series of phasors representing the waves to be combined. Draw them end to end, maintaining the proper phase relations between adjacent phasors. 2. Construct the vector sum of this array. The length of this vector sum gives the amplitude of the resultant phase. The angle between the vector sum and the first
phasor is the phase of the resultant with respect to this first phase. The projection of this vector-sum phase on the vertical axis gives the time variation of the resultant wave.
